Defending a house of worship against a real gunman? That’s a whole different story.

As he led a security training on Tuesday (Dec. 5) at a Dallas-area megachurch, Sgt. Mike Gurley warned against thinking that worshippers licensed to carry handguns can offer reliable protection.

“To assume they’re going to be effective in an active-shooter situation is comparable to giving me a set of golf clubs and expecting me to win the Masters,” the retired Dallas policeman told the crowd of 650 pastors and other church leaders.
